Plant secondary metabolites (SMs) play important roles in plant survival and creating ecological connections between other species. In addition to providing a variety of valuable natural products, help protect plants against pathogenic attacks environmental stresses. Given their sessile nature, must themselves from such situations through accumulation these bioactive compounds. Indeed, act as herbivore deterrents, barriers pathogen invasion, mitigators oxidative stress. The SMs are highly dependent on factors light, temperature, soil water, fertility, salinity. For most plants, change an individual factor can alter the content even if remain constant. this review, we focus how affect during both biotic abiotic stress conditions. Furthermore, discuss application elicitors culture systems well stimulating effects metabolites. Specifically, shikimate pathway aromatic amino acids produced pathway, which precursors range including terpenoids, alkaloids, sulfur- nitrogen-containing We also detail biosynthesis is altered by several genes related metabolite pathways. Genes responsible for various species conditions regulated transcriptional WRKY, MYB, AP2/ERF, bZIP, bHLH, NAC, discussed here.

Monitoring Plant Health with Near-Infrared Fluorescent H₂O₂ Nanosensors

Nano Letters, Год журнала: 2020, Номер 20(4), С. 2432 - 2442

Near-infrared (nIR) fluorescent single-walled carbon nanotubes (SWCNTs) were designed and interfaced with leaves of Arabidopsis thaliana plants to report hydrogen peroxide (H2O2), a key signaling molecule associated the onset plant stress. The sensor nIR fluorescence response (>900 nm) is quenched by H2O2 selectivity against other stress-associated molecules within physiological range (10–100 μM). In vivo remote imaging sensors enabled optical monitoring health in stresses including UV-B light (−11%), high (−6%), pathogen-related peptide (flg22) (−10%), but not mechanical leaf wounding (<3%). sensor's biocompatibility was reflected on similar cell death (<5%) photosynthetic rates controls without SWCNT. These nanosensors early signs stress will improve our understanding communication, provide novel tools for precision agriculture, optimize use agrochemicals environment.

A comprehensive review of transcription factor-mediated regulation of secondary metabolites in plants under environmental stress

Stress Biology, Год журнала: 2025, Номер 5(1)

Опубликована: Фев. 24, 2025

Abstract Plants encounter a wide range of biotic and abiotic environmental stresses throughout their lifespan. To adapt survive, they have evolved complex defense mechanisms that involve the production secondary metabolites (SMs), which play critical roles in enhancing plant resilience. These bioactive compounds function as deterrents to herbivores, barriers against pathogens, protectants oxidative stress. regulate synthesis accumulation (SMs) response various factors such drought, salinity, cold, heat, heavy metals, UV-B radiation. stress conditions can significantly alter SM levels part plant's adaptive response. Transcription (TFs) are essential mediators this process, regulating gene expression involved biosynthesis. By interacting with signaling pathways, TFs fine-tune mechanisms, ensuring timely specific SMs mitigate impacts. This review provides comprehensive examination influence on plants under both conditions. Additionally, we thoroughly discuss key TFs—including AP2/ERF, WRKY, bHLH, bZIP, MYB, NAC—in biosynthesis, highlighting contributions ability withstand

Associational resistance through intercropping reduces yield losses to soil‐borne pests and diseases

New Phytologist, Год журнала: 2022, Номер 235(6), С. 2393 - 2405

Summary Associational resistance to herbivore and pathogen attack is a well documented ecological phenomenon and, if applied agriculture, may reduce impact of pests diseases on crop yields without recourse pesticides. The value associational through intercropping, planting multiple crops alongside each other, as sustainable control method remains unclear, due variable outcomes reported in the published literature. We performed meta‐analysis provide quantitative assessment benefits intercropping for target plant plant‐parasitic nematodes soil‐borne diseases. found that reduced damage focal from by 40% disease incidence 55%. Intercropping efficacy varied with biological variables, such field fertilisation status intercrop family, methodology, including whether study samples were potted or fields. Nematode using was sufficient offset reductions yield presence, making viable agricultural tool. identify key drivers underpinning success indicate areas future research improve efficacy. This also highlights potential harnessing knowledge plant–enemy interactions improving landscape sustainability.

Regulation of the regulators: Transcription factors controlling biosynthesis of plant secondary metabolites during biotic stresses and their regulation by miRNAs

Frontiers in Plant Science, Год журнала: 2023, Номер 14

Biotic stresses threaten to destabilize global food security and cause major losses crop yield worldwide. In response pest pathogen attacks, plants trigger many adaptive cellular, morphological, physiological, metabolic changes. One of the crucial stress-induced responses is synthesis accumulation plant secondary metabolites (PSMs). PSMs mitigate adverse effects stress by maintaining normal physiological functioning plants, thereby providing tolerance. This differential production tightly orchestrated master regulatory elements, Transcription factors (TFs) express differentially or undergo transcriptional translational modifications during conditions influence PSMs. Amongst others, microRNAs, a class small, non-coding RNA molecules that regulate gene expression post-transcriptionally, also play vital role in controlling such TFs. The present review summarizes stress-inducible TFs synthesizing accumulating highlights how miRNAs fine-tune various stress-responsive transcription biotic stress.
